LISTER-CULTIVATOR.

To all whom it may concern:

Be it known that I, Lewis E. TA'I'ERMAN, a citizen of the United States.residing at Rockford, in the county of lVinnebago and State of Illinoishave invented certain new and useful Improvements in Lister-Cultivatorsof which the following is a specification.

The object of this invention is to support the seat of a' listercultivator so that it will always remain centrally between the twosections of cultivating devices.

The further object of this invention is to form a drafthitch with thecultivating de vices in order that the team may cause them toenter theground.

In the accompanying drawings. Figure 1 is a plan view of my improvedlistercultivator. Fig. 2 is, an end elevation. Fig. 3 is an end View ofa shank of one of the disk supports and its connection with its support.Fig. 4 is an elevation of the seat support,

the brackets for the support being in section.

My lister cultivator comprises two like sections, each supportingcultivating devices, and a description of one complete section willapply to both.

A tongue 1 has the frame bars 2 and 3 bolted thereto. To the free endsof these bars are pivoted intermediate sections 4 which are connected bythe square bar 5. To the rear ends of these intermediate sections ispivoted to the rear section 6 of the frame.

To the square bar 5 areconnected two carrying wheels 7, their shanks =8being clamped thereto by the clamps 9 and U bolts 10. To the square bar5 are clamped two shanks 11 to which are connected the disks 12. Theclamps holding these shanks are in two sections 13 held together and inconnec The outer surface of the shanks 11 are formed with serrations 15in which the edges of the sections 13 are seated, and which admit of theshanks being adjusted axially thereby presenting the disks in differentangles to the ground: To the square bar 5 between the carrying wheels 7is secured a toothed segment 16, and a hand lever 17 has a pivotalconnection with the segment and is provided with theusual dog and thumblatch connection with the lever. This hand lever 17 is provided with arearward extension 18. To the section *3 of the frame Specification ofLetters Patent.

are secured shovels 19 which are located in rear of the disks 12.

nection with the shanks S of 'the carrying wheels 7, and a chain 21connects it with.

the extension 18 of the lifting lever 17. A link 22 connects theextension 18 with the rear section 6,0f the frame.

By means of the hand lever 17. the rear section 6 of the frame is raisedor lowered in its pivotal. connection with the intermediate section 4supporting the square bar 5. The shovels 1S) and shield 20 will beraised and lowered therewith.

Around the tongue 1 is located a slidahle yoke 23 to the underside ofwhich is connected a hitch 24 to which the evener may be connected. Rods25 form connections between the yoke 23 and the shanks 8 of the carryingwheels. A toothed segment 26' has a fixed connection with the yoke 23and a hand lever 27 has a pivotal. connection with the toothed segmentand is provided with the usual dog and thumb lever'for holding it A.shield 20 has a con-.

in engagement with the toothed segment.

A bracket 28 is secured to the upper face of the tongue 1 and a rod 29connects this bracket with the hand lever 27.

- By means of the hand lever 27 the relative position of the yoke 23with respect to the bracket 28 may be changed. and when moved toward thebracket 28 the carrying wheels 7 will be moved rearward which will rockthe square bar 5 and the toothed segment 16 and disks 12 connectedtherewith. and through the connections between the lever 17 and the rearframe section 6, the shield 20, and the shovels 19 will. be raised. Byreleasing the hand lever 27 from its engagement'with the toothed segment26 of the yoke. 23, the team connected to the hitch 24 will force thedisks and shovels 19 into the ground.

In each of the brackets 28 is located the section 30 of a substantiallyZ-shaped. bracket 31, and the other end 32 is clamped in .a socket 33.The sockets 33 are clamped to a seat bar 34 which connects the two toolsupporting sections of the lister cultivator. A

seatsupport 35 is fixedly clamped to the seat bar 39, and a seat 36 hasa connection with the seat support.

To the lower end of the seat. support is pivoted a cross-bar 37.Sectional links 38 have one end gz-ivotaily connected to onposite endsof the cross-bar 3?, and the links 38, and the swinging brackets 31.Without the equalizing devices comprising the seat support 35, cross-bar37 and links 38, the seat-bar 34-, and seat 36, supported thereby wouldswing laterally of the tongue 1,,and should one of the tool supportingsection's be lower than the other, the seat would swing toward thatsection. Should the other section become the lower, the seat would thenswing toward with spaced tool supporting sections hav ing sockets, of aseat bar extending transversely thereof, and having sockets, and substantially .Z-shaped brackets each formed of a single rod having adepending end journaled in the socket of one of the tool-supportingsections, and an upstanding end journaled in a socket of the seat bar.

2. In a lister cultivator, the combination of a tongue, a toolsupporting section connected with the tongue carrying wheels for thesections, a yoke slidably mounted on the tongue, a toothed segmentsupported by the yoke and slidable therewith, a hand lever pi voted tothe toothed segment and provided with means for engaging with thesegment, a connection between the lever and tongue, and connectionsbetween the yoke and supporting wheels.

In a lister cultivator,

the combination with a tongue membeijof a frame bar pivotally connectedthereto, ground wheels, tool elements connected to the frame bar, areciprocatory yoke slidable on the tongue member, a link pivotallyconnecting the yoke and bar, a lever onand reciprocating with the yoke,and a connection between the lever and the tongue member forreciprocating said yoke and thereby effecting the pivotal movement ofthe bar and the swinging movevment of the wheels and tool elements.

4-. In a lister cultivator, the combination with a tongue, of a swingingtool support pivotally connected thereto, ayoke slidably mounted on thetongue, a link pivotally connected to the yoke and the tool support, alever fulcrumed on and slidable with the yoke, a link pivoted to thelever and to the tongue, and means for connecting the yoke and. lever tohold the latter in di-iferent pohitions, said lever constituting meansfor reciprocating the yoke. l

' 5. In a lister cultivator, the combination with a tongue having aframe, of across bar pivotally connected'thereto, a rear section pivotedto the cross bar, tool elements and ground wheels mounted on the crossbar and rear section, a lever fulcrumed on the cross bar and havingconnections with the rear section for swinging the same with respect tosaid cross-bar, a yoke slidably mounted on the tongue, a link connectionbetween the yoke and the dress bar, a lever fulcrumed on the yoke, meansfor holding the lever in different positions on the yoke and a linkconnection between the lever and the tongue. In testimony whereof I havehereunto set my hand in presence of two subscribing witnesses.
